Attean::BindingEqualityTest - Test for equality of binding sets with bnode isomorphism
This document describes Attean::BindingEqualityTest version 0.016
use v5.14; use Attean; my $test = Attean::BindingEqualityTest->new(); if ($test->equals($iter_a, $iter_b)) { say "Iterators contain equivalent bindings"; }
...
equals ( $graph1, $graph2 )
Returns true if the invocant and $graph represent two equal RDF graphs (e.g. there exists a bijection between the RDF statements of the invocant and $graph).
is_subgraph_of ( $graph1, $graph2 )
Returns true if the invocant is a subgraph of $graph. (i.e. there exists an injection of RDF statements from the invocant to $graph.)
injection_map ( $graph1, $graph2 )
If the invocant is a subgraph of $graph, returns a mapping of blank node identifiers from the invocant graph to $graph as a hashref. Otherwise returns false. The solution is not always unique; where there exist multiple solutions, the solution returned is arbitrary.
split_blank_statements( $iter )
Returns two array refs containing bindings from $iter, with bindings containing blank nodes and bindings without any blank nodes, respectively.
$iter
